if you are selecting body/portrait manually make sure you check 'Assign both'
Viewing post in Old: Not so Random Portraits
I have that selected. I've used these types of mods before and on S4P. Turns out, it's ONLY when I click random so if I manually select a portrait it matches just fine, but if I'm hitting random it seems to have an issue. The issue was worth with the Optimizer too, which might mean that I'm just trying to cycle too quickly or something and it's not keeping up and matching the two until it can catch up again xD Either way, if I just click one manually it works fine so no big deal just a little odd how it's doing it.
